Analytical Programs

Basic Characterization (validity for 8 to 10 years)

With the Basic Characterization, dynamic processes in the soil are analytically depicted and assessed. The results are used to deduct measures and recommendations to optimize and sustainably preserve soil fertility. This analytical program is recommended to characterize the status quo of the fertility of the soil under investigation. Furthermore, it is possible to evaluate changes in agricultural practices, fertilization strategies etc.

All information and results of the analytical program “Current Nutrient Supply” is included in the program “Basic Characterization”.

You will receive the following information:

  • Is the actual nutrient supply sufficient to nourish the current / planned crops?
  • Are the nutrients in equilibrium?
  • Is it necessary to fertilize nutrients? Is it possible to mobilize nutrients (e.g. phosphorus)?
  • Which acid buffer system is prevalent in the soil (liming yes/no)?
  • What is the humus level of the soil? How high is the quality of the humus?
  • Which milieu conditions are in place for soil organisms?
  • Is the potential of the specific site fully utilized?
  • Is soil fertility preserved in a sustainable manner?
  • Are the soil functions (e.g. ground water protection, flood protection) performed properly?
  • Is there any hidden hazardous potential (e.g. potentially toxic substances)?
  • How does the soil react to the application of liquid and solid biogas residues?

Current Nutrient Supply (validity for 2 years)

The analytical program “Current Nutrient Supply” evaluates the actual nutrient supply and helps to optimize the fertilization strategy.

You will receive the following information:

  • Is the actual nutrient supply sufficient to feed the current / planned crops?
  • Are the nutrients in equilibrium?
  • Is it necessary to fertilize nutrients?
  • Which acid buffer system is prevalent in the soil (liming yes/no)?
  • What is the humus level of the soil? How high is the quality of the humus?
  • Which milieu conditions are in place for soil organisms?
  • Is there any hidden hazardous potential (e.g. potentially toxic substances)?

Assessment of Soil

A professional assessment of soil examines the suitability of sites and fields for the designated utilization, e.g. before a leasing or purchase contract is signed. Furthermore, soil assessments are carried out in the course of environmental impact assessments. For example, in the planning of a biogas power plant, the fertility of the soils is often unattended. While some soil types are able to handle biogas residues such as liquid and solid residues of the fermentation process very well, other soils possibly suffer a loss of soil fertility and crop yields after the application of biogas residues.
The soil expertise in this exemplary case helps to clarify if biogas residues sustainably damage soils or if the desired fertilization effect is accomplished.

A soil evaluation can be useful to clarify the suitability of the assessed soil for the intended use before buying or leasing a property.

Soil surveys are also provided in the context of environmental impact assessments (EIAs).

Range of parameters:

Depends on the specific question and task.
